Dual 3in (72mm) paths flow uninterrupted with the valves open, while a smaller 2.5in (63.5mm) closed-valve path and an integrated Helmholtz resonator reduce volume and drone when cruising. Valve-controlled rear mufflers adjust sound to driving style, and APR measures gains of 9 HP and 16 ft-lbs at all four wheels. Quad exits feed dual 8.23x4.76in RS-style diamond black oval tips with an APR logo.\u003c\/p\u003e\u003ch2 style=\"margin:16px 0 4px 0;\"\u003eSpecifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse;width:100%;margin-top:0;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eCatalyst-back exhaust system, valved (includes downpipes)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eT304 stainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eFinish\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eBrushed, with 8.23x4.76in diamond black oval tips\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eQuantity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;\"\u003eCBK0050\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp style=\"margin-top:12px;\"\u003eThis part fits:\u003c\/p\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" width=\"100\"\u003eYear\u003c\/th\u003e\n\u003cth align=\"left\" width=\"125\"\u003eMake\u003c\/th\u003e\n\u003cth align=\"left\" width=\"150\"\u003eModel\u003c\/th\u003e\n\u003cth align=\"left\" width=\"80\"\u003eSubmodel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2021-2023\u003c\/td\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eRS6 Avant\u003c\/td\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2025\u003c\/td\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eRS6 Avant\u003c\/td\u003e\n\u003ctd\u003eGT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2024-2026\u003c\/td\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eRS6 Avant\u003c\/td\u003e\n\u003ctd\u003ePerformance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2021-2023\u003c\/td\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eRS7 Sportback\u003c\/td\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2024-2026\u003c\/td\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eRS7 Sportback\u003c\/td\u003e\n\u003ctd\u003ePerformance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"APR","offers":[{"title":"Default Title","offer_id":46808517574828,"sku":"APRCBK0050","price":3099.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0480\/2160\/2467\/files\/3fa64f3cfe4eaa94c5df3791fcacd794L.jpg?v=1784796659","url":"https:\/\/onefastshop.com\/products\/apr-stainless-steel-cat-back-exhaust-audi-rs6-rs7-c8-2021-2026-diamond-black-tips","provider":"OneFastShop","version":"1.0","type":"link"}
